Cows may suffer impaired ovarian function, often accompanied by reduced conception rates and increased embryonic loss. Cystic ovarian disease (COD) is one of the most frequently diagnosed gynecological findings in dairy cattle. It causes temporary infertility and is likely to affect reproduction as well as production parameters in cattle. Therefore, the purpose of this study was to determine the expression patterns of apoptosis (Bcl-2, Bax), implantation (E-cadherin) and immune related proteins (TNF-α, IL-10) in uterine endometrium of Hanwoo (Korean native cattle) with ovarian cyst and normal ovarian follicles. In the Western blot analysis, the expression of anti-apoptotic Bcl-2 protein was significantly higher in endometrium with normal ovarian follicles, whereas expression of pro-apoptotic Bax protein was significantly lower. Also, the expressions of E-cadherin and TNF-α proteins were significantly higher in uterine endometrium with normal ovarian follicles. On the other hand, the expression of IL-10 protein was significantly lower in uterine endometrium with normal ovarian follicles. Taken together, our results provided that the expressions of apoptosis, adhesion and immune related proteins in uterine endometrium with ovarian cyst were showed the aberrant patterns, and we suggest that different expression changes of these proteins may be affect to pregnancy ability of cattle.
